SPECIFICATION forming part of Letters Patent No. 474,285, dated May 3, '1892. Application filed January 29,1892. Serial No. 419,645; (No model.) i

1'0 all whom it may concern; 7

Be it known that I, CYRUS BORGNER, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Bricks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable ot-liersskilled in the art to which it appertains to make and use the same.

My present invention relates to the construction of brick, and has especial reference to fire-briek designed for use in walls for lining inetallurgic, glass, or boiler furnaces; out it may also be applied to brick for general purposes.

The object of the invention is to construct a brick that will bind -t=hc courses togetherand that may be used to form a bond in any position the brick may be laid.

In the practical use of furnaces where a high degree of heat maintained the lining is subject to great expansion, and unless the brick are properly bonded or tied together they become displaced, and attany and all events theheat and wear, in conjunction with the expansion and contraction of the wall or lining, cause the brick to deteriorate, more or less, according to quality, and require renewmg.

The brick in ordinary use [or t'urn aco-lin ing are easily displaced tor the reason they are either not bonded at all oronly in courses.

The invention will be fully disclosed in the following specification and claims. In the accompanying drawings, which form. part of this specification, Figure l is a per spcctive of my improved brick; Fig. 2, a vertical longitudinal section; Fig. 3, a top plan view of a modification; h" i, an inverted plan view of the same; Fi 5, a vertical longitudinal section through two brick of the latter construction; Fig. 1', a pcrspectivcof a four-inch wall or lnrnacediuing constructed of my improved brick; Fig. 7, a similar view of a nineinch wall; Fig. 8, a bottom plan view of a brick provided with transverse grooves for use as headers; and l ig. 9, a similar view of a brick provided with longitndinal grooves for use as stringers, as will hereinaitcr more fully appear.

--Reference being had to the drawings and the letters thereon, A indicates a brick, which may be called a universahbond brick, and provided on one side with a plurality of spurs or projections a, which are arranged in pairs and are equidistant from each other 1 longitudinally and transversely on the brick,

and the distance from the ends and sides of the brick to the spurs is equal to one-half the distance between any two spurs, and on the other side of the brick and directly opposite the spurs (tarev depressions I), which correspond with the spurs and form seats with which the spurs on an adjacent brick engage.

.lly spacing the spurs and depressions and arranging them in pairs, as shown and described, the brick may be placed one on top of another in any position required in construetiing a wall that shall be straight or at any right angle, as is shown in Fig. 6, and in constructing a nine-inch or a thicker wall the stringers and headers are seen rel y bonded or tied together.

in Figs. 3, 4, and 5 I have shown a modification of the construction shown in Figs. 1 nut 23. Inthelatterconstruction one surface or side is provided with longitudinal ribs or projections c and transverse ribs or projections J, which are ata right angle to each other and intersect, and on the other side of the brick and directly opposite the ribs 0 (Z are corresponding grooves or depressions cf. This brick may be used where the appearance of the ribs and grooves will not be objcetionablc.

To provide [or repairing lire-hriok walls or linings for furnaces without tearing down the wall or lining, some of the bricks A are provhled with transverse grooves or depressions g, which aredireetlyopposite the spurs (t, and others with longitudinal grooves 71. The ap plication of these two forms of bricks isshown in Fig. 7, in which a heading-course is shown with the grooves l/ and a stringer with the grooves it. by applying these bricks in the manner shown new bricks may be inserted in any part of a wall underneath the headers that may require renewing without interfering with partscl the wall above. The spurs and depressions maybe varied in number so long as they are preserved in pairs arranged standard brick the number may be increased.

Bricks constructed as-described are-adrnirably adapted for constructing walls, the projections and depressions beingof such height and depth as to allow the bricks to lie close upon each other and to bind the brick so that lateral displacement of bricks from a course is impossible.

\Vhen used in walls for buildings, a thin layer of cement or mortar may be used without interfering with the projections and depressions. e

Having thus fully described my invention, what I claim is. i

1. As an improved article of manufacture, a'brick provided with projections arranged equidistant, and in a plurality of pairs ononc side and corresponding depressions in the opposite side. l

2. As an improved article of manufacture, a brick provided with projections arranged in a plurality of longitudinal and transverse equidistant pairs on one side, and corresponding depressions in the other side and opposite said depressions.

3. A brick provided with aplurality of pairs of projections arranged equidistant longitudinally and transversely of the brick and on one side thereof, and grooves in the opposite side of the brick.

In testimony whereof I aflix my signature in presence of two witnesses.

CYRUS BORGNER.
